Integrated graphics help


Ok, I installed Ubuntu a few days ago. Been having fun learning linux, but an issue I have come across I can't seem to figure out. My integrated graphics chip is an old intel 815. It was not being utilized properly for some reason, so I went into system setting to make sure linux detected it. I clicked it in the list of supported chip sets in the system settings. It told me to do a x server restart. Did that, now it won't load back into a graphical user interface (kde 3.5). I can get into terminal konsole just fine doing a normal non ugi boot. Is there any way for me to fix this or simply undo what I did from terminal? And before anyone asks, I am still learning a lot about linux and am not good with the terminology just yet. Thnx for any help.

Try sudo /etc/init.d/kdm start.

You may need to follow that up with init 5 or startkde.

Have a look at your /etc/X11/xorg.conf file with this command:
less /etc/X11/xorg.conf, in the Device section under driver (use arrow keys or scroll wheel on mouse to scroll down to the Device section), make sure it's "i810", an example below.
Code:
Section "Device"
    Identifier  "Whatever"
    Driver      "i810"
EndSection
If not, you may want to edit this file to use the generic Intel driver i810.

ok...

That worked. Reset the driver. By the way, what is the term in linux for driver? Graphics controller? Now, I am a bit confused here. I put in an old nVIDIA TNT2 card that has just 8mb of memory, and I am getting loads better performance then my intel 815 which had 32mb. Can anyone explain this? Seems to me I would have been better off with the integrated graphics. Not that I am complaining, just curious.

Everything in any operating system is initialized by the kernel. Some drivers (Windows talk)/modules (Linux talk) are built into the kernel and are initialized right from boot-up, many "not so necessary" type modules are loaded into the kernel dynamically (when they are needed). It's relatively simple for someone interested in knowing about it.

BTW:
I know nothing about that ancient Nvidia card you have, and I may have it also in my collection. But I have a few high end jobbers with Nvidia Go 6800 and Nvidia GeForce 8600GTS that I use on a day to day basis. Best damn graphics there ever was.
But, I'm guessing your processor is no slouch, because most graphics cards that are limited to that much memory allocation mostly rely on processor capabilities for better performance.

Damn!
No sooner after I hit Post reply I turned a couple pages in a London Drugs flyer and seen an add for a NVidia GeForce 9600GT OC 512MB GDDR3 PCI E 2.0 Card for $199.99. I'm sure I paid something like $250.00 for my 8600GTS....which is an overclocked card....probably still out-performs the next generation GT series...'I hope'.

Well, I do not play any computer games any more. I like to watch a lot of music videos on youtube. My tnt2 works ok for it, but if my integrated graphics will do the job better then I would like to do it.

BTW:
The generic Linux Nvidia driver is "nv", try that with the Nvidia card to see if it out-performs the integrated graphics.

Forgot to mention,
The Intel 82810-82815 chip sets only allocated 8MB of memory to graphics also, chances are the PCI Nvidia should out-perform Intel's "stable, reliable" i810 performance.
